Java7 Features

In this Tutorials we are going to see what are the changes and new features comes in Java7.

Virtual Machine :

JSR 292: Support for dynamically-typed languages (InvokeDynamic)Extensions to the JVM, the Java language, and the Java SE API to support the implementation of dynamically-typed languages at performance levels near to that of the Java language itself

Strict class-file checkingAs specified in JSR 202, which was part of Java SE 6, and in the recently-approved maintenance revision of JSR 924, class files of version 51 (SE 7) or later must be verified with the typechecking verifier; the VM must not fail over to the old inferencing verifier.

Security & Cryptography

Elliptic-curve cryptography (ECC)A portable implementation of the standard Elliptic Curve Cryptographic (ECC) algorithms, so that all Java applications can use ECC out-of-the-box

Database Connectivity

JDBC 4.1Upgrade to JDBC 4.1 and Rowset 1.1

Client

XRender pipeline for Java 2DA new Java2D graphics pipeline based upon the X11 XRender extension, which provides access to much of the functionality of modern GPUs

Create new platform APIs for 6u10 graphics featuresCreate new platform APIs for features originally implemented in the 6u10 release: Translucent and shaped windows, and heavyweight/lightweight component mixing

Gervill sound synthesizerDrop the old, proprietary, encumbered sound synthesizer in favor of Gervill, a synthesizer created as a proposal for the Audio Synthesis Engine Project

Web

Update the XML stackUpgrade the components of the XML stack to the most recent stable versions: JAXP 1.4, JAXB 2.2a, and JAX-WS 2.2

Management

Enhanced MBeansEnhancements to the existing com.sun.management MBeans to report the recent CPU load of the whole system, the CPU load of the JVM process, and to send JMX notifications when GC events occur (this feature previously included an enhanced JMX Agent, but that was dropped due to lack of time)
